Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11722, here are decompositions:

3 + 11719 = 11722
5 + 11717 = 11722
23 + 11699 = 11722
41 + 11681 = 11722
89 + 11633 = 11722
101 + 11621 = 11722
173 + 11549 = 11722
233 + 11489 = 11722

Showing the first eight; more decompositions exist.
